Other than just holding the iPhone in the car for you, the AssistOne also supports hands free talking and voice activation for controls. The device also amplifies turn-by-turn directions, which is a feature that is required if you have ever tried to use an iPhone for a GPS device in a car.

The device pairs to the iPhone using Bluetooth for calling and media playback. The voice controls let the user answer or decline a call using iPhone Voice Control. Specifications include Bluetooth v 2.1 + EDR with 5V DC inputs and the case will work with all iPhone models, not just the iPhone 4 as well as the iPod touch , nano, and video music players.
